THRESHING-MACI-IINE.

Application filed July 18, 1911.

vented new and useful Improvements in- Threshing-Machines, whichimprovements are fully set forth in the following specification.

In Letters Patent No. 96%,966, issued to me under date of July 19, 1910,a threshing machine is described; by means of which, after cuttingcereals, the grains thereof and the stalks could be separatedimmediately. The said improvement consisted chiefly in the use, in placeofthe reed or comb or combs, of a threshing device, characterized by aperforated frame constituted of a grating, or perforated sheet metal ormade of wooden or metal rods, to which a reciprocating motion relativelyto another frame formed of wood or metal rods was communicated by meansof any suitable mechanical transmission, the whole system being arrangedat the back of the tractor system with bands consisting of endlesschains, cables or belts, in the central plane of which band the framewith rods could be either fixed or have a reciprocating or hammering orany other motion suitable for assisting the threshing operation.

This invention has for its object to sub stitute for the threshing workdone by means of combs, a rotary beater or threshing cylinder whichtakes the cereals either transversely to the stalks, or parallel withthe stalks, in combination with a concave below the threshing cylinderand a tractor system consisting of inclined feed-aprons and means formoving them toward the threshing cylinder and concave.

Figure l is a perspective view of one construction in which the axis ofthe threshing cylinder is at a right angle to the stalks of the cereals,and Fig. 2 is a perspective view of another construction in which theaxis of the threshing cylinder is parallel to the stalks of the cereals.

In the construction shown in Fig. 1, the threshing cylinder is arrangedat the back of the tractor system 1 provided with bands consisting ofendless chains, cables or belts. This threshing cylinder has the usualconstruction, that is to say, is constituted by wooden or metal bars 2supported by arms 3 radiating from a spindle at.

is connected by a suitable transmission gear to the driving axle, andthe circular path in which the bars 2 travel, is partly closed by asheet metal plate or concave 5 separated from the threshing cylinderonly by a very small distance. This plate or concave is, of course, bentin accordance with the path of the bars 2, and is also perforated andpro- .vided with metal bars or rods which oppose their resistance to thegrain carried by the threshing cylinder and at the same time affordpassage for its discharge. In this construction, the threshing cylinderand the concave being arranged at a right angle to the direction inwhich the bands of the tractor system 1 rise strike therefore only theportion of the stalks of the cereals which has not been seized by thesaid chains.

The threshing cylinder and the concave can also be arranged, as shown inFig. 2, parallel to the tractor system or to the conveyer bands of anordinary binder and located where the stalks emerge entirely from thebands. In such an arrangement, the entire stalks and not a portionthereof are driven by the threshing cylinder between the latter and theconcave.

In the first construction (Fig. 1), the length of the threshing cylindermust be calculated in proportion to that of the tractor apparatus. Inthe second construction (Fig. 2), this length must correspond to thegreatest length of the stalks which are treated entirely, as is done inordinary threshers.

Obviously the direction of rotation of the bars 2 relatively to thebands or chains varies according to the position of the threshingapparatus. When the threshing cylinder is at a right angle (Fig. 1) itdrives the grain downward; when the threshing cylinder is parallel (Fig.2), it raises the stalks.

The separated grain is received in any suitable casing surrounding theconcave, be low the same, and which is omitted for the sake of clearnessin the drawings, as are also omitted numerous other parts going to makeup the machine, all of which are well known without detail description.

I claim- In a threshing-machine of the character described, thecombination, with a tractor comprising two inclined feed-belts in closeproximity and adapted to securely hold the stalks between them, andmeans for moving the belts in upward direction, of a rotary'specification in the presence of two subthreshing cylilnder supported atthe'sicfleof scribing Witnesses. said belts wit lin threshing distance 0the stalk heads projecting therefrom, and hav- ABERRY 5 ing its axisparallel with the direction of J travel of the feed belts, and a concavein Witnesses: proximity to the threshing-cylinder.
